Description: Coming from the Cambrian Wheeler Formation deposits of Millard County Utah this is a detailed example of the trilobite Asaphiscus wheeleri. These trilobites are often found with disarticulated or missing free cheeks. These fine examples are well-articulated, with a dark black exoskeleton which contrasts well with the grey shale matrix which derives its color from its high organic content.
